About the Airtac SAID80 Double Rod Cylinder SAID80X165S
The AirTAC SAID80X165-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 80mm bore and 165mm stroke. A single piston drives a carbon steel rod out of both end covers, yielding identical annulus areas. This architecture provides equal push and pull forces, generating 2268N of thrust in each direction at 0.5 MPa and 4082N at 0.9 MPa.
Equipped with the -S magnet option, this unit integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches via the dual-side sensor grooves. The extruded aluminum barrel keeps the assembly lightweight while offering a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. It operates on filtered air at speeds between 30 and 800 mm/s.

Where the Airtac SAID80 Double Rod Cylinder SAID80X165S Is Used
Symmetric Force Transfer
Drives a workpiece forward and backward with identical 2268N force at 0.5 MPa, ensuring balanced momentum and consistent cycle times in both directions.
Anti-Rotation Slides
Utilizes twin rods exiting both end covers to provide dual-side guidance, effectively resisting torsional twist and maintaining precise load orientation.
Dual-Station Actuation
Mounts the primary tool on the front rod and a secondary cam or position flag on the rear rod to trigger external reed or electronic sensors simultaneously.
Is the Airtac SAID80 Double Rod Cylinder SAID80X165S the Right Cylinder?
Select this 80mm bore when an application demands symmetric force and speed for extending and retracting, offering 2268N both ways at 0.5 MPa. If your mechanism requires less force, stepping down to the 63mm bore provides 1402N each way, while moving up to the 100mm bore yields 3681N. The double-rod design is chosen over a single-rod SAI when dual-side guidance is needed to prevent load rotation, or when a rear cam and position flag must be driven alongside the primary workpiece.
As a dimensionally interchangeable ISO 15552 component, it serves as a drop-in replacement for other standard profile cylinders, utilizing a PT tapered G3/8 port. Note that a plain SAID cylinder does not hold its position if air pressure is lost; for load-holding requirements, consider the SAIL or BSAID variants. Because the rear rod protrudes from the back cover, ensure you leave adequate clearance for the full stroke length.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID80 Double Rod Cylinder SAID80X165S FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. The push and pull forces are equal, providing 2268N at 0.5 MPa, 3175N at 0.7 MPa, and 4082N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other profile cylinders. However, it does not hold its position if air is lost; for locking requirements, look at the SAIL or BSAID models.
